Know the Answer?

Allan Arnold · Answer 1

The process for coating metal like iron or steel with a thin zinc layer is known as galvanization. The zinc layer serves to protect the metal from rusting

Kelvin Christensen · Answer 2

Since zinc is more reactive than iron, when we galvanize iron with zinc, zinc react with oxygen to form a thin layer of oxide which prevents metal to further corrosion. That thin layer of zinc oxide will protect iron from rusting.
